Abstract: Olive anthracnose caused by Colletotrichum spp. is a disease currently becoming important in the Mediterranean region. In Portugal, the disease is responsible for important olive yield loss and poor oil quality. The objectives of this work were to establish a collection of Colletotrichum spp. isolates representing the causal agents of this disease in Portugal, as well as analyse the genotypic and phenotypic diversity at the species level. A total of 40 isolates were obtained representing 18 locations in the south and centre of the country. This collection was analysed according to different parameters: morphology (shape and size of conidia), culture (growth rate on PDA medium, colony characteristics and response to benomyl), pathogenicity and virulence (in olives and other hosts) and molecular data (rDNA ITS species- specific primers). The species C. acutatum was more commonly isolated from olives, but C. gloeosporioides was also identified
